For logging the water depth, users need a black box for doing this...

There are several systems of navigation instruments on board:

1. NMEA-0183 with single GPS and single sounder
2. NMEA-0183 export from a chart plotter, with connected GPS and sounder
3. NMEA-2000 with connected GPS and sounder
4. Chart plotters writing to an SD-card, (W)LAN or USB, with connected GPS and sounder

We need two HW-Loggers:

NMEA-0183
NMEA-2000

Skipper with PC and NMEA-0183 can use our SW-Logger (plus RS-232>USB converter).
